Interesting, I'm _extremely_ happy with Github Actions. But I have pretty basic needs, admittedly.
You mention buildkite as something you think is a lot better than GH Actions. I'm curious if you've also used the Gitlab equivalent and can compare (I haven't, really).

I would not not say buildkite is better, per se. I'd say it's more mature and much more flexible. Buildkite is easily "programmable" in a way that GHA is not. That flexibility is important for advanced/large scale use cases.
